# dragnn_ops.extract_fixed_features(handle, channel_id, component=None, name=None)
### `dragnn_ops.extract_fixed_features(handle, channel_id, component=None, name=None)`
Defined in `tensorflow/dragnn/core/ops/gen_dragnn_ops.py`.
Given a handle to a ComputeSession and a channel index, outputs fixed features.
Fixed features returned as 3 vectors, 'indices', 'ids', and 'weights' of equal
length. 'ids' specifies which rows should be looked up in the embedding matrix.
'weights' specifies a scale for each embedding vector. 'indices' is a sorted
vector that assigns the same index to embedding vectors that should be summed
together.
#### Args:
* `handle`: A `Tensor` of type `string`. handle to a ComputeSession.
* `channel_id`: An `int`. feature channel to extract features for.
* `component`: An optional `string`. Defaults to `""`.
* `name`: A name for the operation (optional).
#### Returns:
A tuple of `Tensor` objects (indices, ids, weights). * `indices`: A
`Tensor` of type `int32`. row to add embeddings to. * `ids`: A `Tensor`
of type `int64`. lookup indices into embedding matrices. * `weights`: A
`Tensor` of type `float32`. weight for each looked up embedding.
